or drawn through the apparatus, and more especially to those designed to electrify air and transform a portion of ozone. 7

The object of my present invention is to produce the electrization of the air, gases, or vapors in the inner part of a body of air or gas, and is arranged in such a manner that the ap aratus' itself sucks in the gases to be electri ed and delivers them after they havebeen electrified into the same body of gas,

air, or vapor.

' My invention is essentially distinguished from those already known and used by the.

fact that the'device itself sucks in the gas to be electrified, while in the previous apparatus the gas is furnished to the devices by a separated com ressor. It is therefore essential not to co ound this device with the apparatuses wherein the electrodes are movable without having another action on the gases than that of electrization, while the resent device sucks in, electrifies, and deiver's the gas to be treated in a single 0 eration andinthe same a paratus. Eveni the as to be treated is fed under pressure it still iiiers from the known devices in that the compressed gas entering the device serves by its expansion. to, move the electrified members, while in the known devices the comdevices as no motive action on the movab e electrifying members. The first arrangement of apparatus may be considered as a ventilator and the secondas a turbine, andv both are adapted, owing to a convenient arrangement. of the blades, to electrify the gas which K The invention consists of novel structural features and relative arrangements thereof,

which will be more fully described hereinafter and then pointed out in the a ended claims.

A. practical embodiment o t e invention is represented in the accompanying three sheets of drawings, forming a part of. this the oxygen intospecification, in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a side elevation of the apparatus. Fi 2 is a vertical section on line 2 2 of Fi 3. i 3 is a vertical section on line 3 3 of ig. 4. ig. 4 is a horizontal section on line 4 4 of Fig. 3, and Fig. 5 is a diagrammatic view showing the manner of connecting up the electrical connection with the apparatus and mode of operating the same.

My device comprises a casing, of porcelain, glass, or any other suitable insulating material, having the usual form of the shells of centrifugal fans or ventilators. This casing is preferably formed or divided in two parts by means of two sections C D, which arese arated in the center by a plane erpendicu ar. .to the axis of the machine.

he sectionsG D are fixed together b any suitable means passing through boltoles H. Separating and interpose between the two sections is a fine glass diaphragm I, of glass, mica, or other suitable dielectric, which, it will be seen, consequently divides the casingof the fan or ventilator in two equal cham ers. In this enmay rotate a movablefwin ed shaft, consists of an insulating-hu ber,

suitable material,s'uch as ebonite,

v steatite, porcelain, &c.-and is provided at each end with metal sockets K K, connected 1 with the steel shafts T T by screws ac. (See Fig. 3.) This hub .J is rotatable by means of beln supported in lubricating-bearings L L,

fixe on each side of the casing at the open- M M and two small bosses N on the easing, which are adapted to engage with two notches in the rings M, thereby maintaining the hearings in their applied position. On the metal sockets K K, inclosing the insulating-hub J, are fixed strai ht or curved wings R R, of metal, referalfiy aluminium, and

connected to eac other by means of an annular plate or crown S. On the diaphragm I there are two series of wings R'R, one on t the'pomt where the shaft pierces the dia hragm 1 there is provided an opening or hole 'O,-sl1ghtly larger in diameter than that of the insulating-shaft J. Two insulating-rings P,

in s of the fan or ventilator. The bearings L are fixed to the casing lg means of rings 50 v whrc may e varied ac'c'ordi P, integral with the shaft, prevent discharges in the form of sparks between the win R R.

' For this same reason the wings are C-s aped,

dia hragm.

eferring to Fi 5, 1 is alow-voltage source of ee'ctrica energy. 2 is an interas shown at Q, and have for their object to facilitate the entrance of the gases from the admission of'the ventilator to the interior of the same to'be acted upon by the wings R B. Holes V V are provided in the foot-p1eces of the halfsections of the casing to s ecurethe apparatus on a suitable base.

From the foregoing description it will beseen that the ventilator or fan is composedof a casing which is non-conducting and the wings or fans of which are in duplicate. Y The axis of the apparatus is insulated and is pro vided with two metal sockets which are insulated from each other, each carrying a series of wings, and the casing of the fan or ventilator is divided centrally into two e ual chambers by means of a vertical dielectricalrupter. 3 is a high-voltage transformer; 4,

the] electrifyingventilator or fan; 5, the motor actuating the wings of the ventilator or'fan, and 6 is the source ofelectricity-supplyfor actuating the motor. If the shaft 5- is rotated more or less rapidly, the system constitutes an ordinary ventilator or fan; but if each of the bearings T T is connected by -means of-the terminals U U tothe poles of an electric generator of high pressure and frequency, as indicated in Fig. 5, a disruptive discharge will be produced in the form of an emanation between the edges of each wing and the opposed ed as shown by small dashes a a, in Fig. 5. Briefly stated, the apparatus is an electrifier and um for the gas it electrifies. If in-' stea of caving the admissions open to the free air they-are connected to the conduits, the gas or vapor to be electrified may be sent through the ventilator instead of air, and the gas or vapor ma be collected at the mouth endof the venti ator and utilized according to the requirements. As the electric action is a more efficacious one when cold, the insulating-casing may have a double wall with a site directions relativel to each other.

wings integral with the same axis.

fluid circulating beneath it, to the speed and to the electric energy sup ied.

I do not care to limit myself in havin the hey may be made independent and turn in oppo-. In wings or blades is refri eratin this case the curve of t contrary to those turning in the opposed direction. I may also dis ose a num er of series ot wings separated h diaphragms, each-series eing electrified in an opposed sense to the next adjacent one.

Instead of having the ventilator driven by a motor I may also compress the gas and utilize its expansion to drive the wings of the on the same generator,

means of several material, each section hit-Vilifi ventilatorby reaction, in which case the ventilator would act as a turbine.

. As the gases by expanding are cooled they are in as favorab e a condition as possible for the electrization. It is important here also not to confound this arrangement, which, if it uses a gas under pressure instead of sucking it in and delivering it as in the firstde scribed case, is very different from the apparatuses into which the gas is introduced with a pressure just sufficient for circulating through the electrifyin members; but where this pressure is not a cient for acting upon and moving blades arranged like those of a turbine the expansiveaction of the a'ses may be sufliciently powerful for allowmga art of the-mechanical energy being taken h'om the shaft and used, if desired, for actuating the source of electricity.
